Firmware upgrade system and method in a device management architecture

A device firmware upgrade method, comprising:

• transmitting from a server to a mobile communications device, using a first protocol, identity information of an upgrade server adapted to operate with respect to said mobile communications device in a second protocol;
• receiving, at said upgrade server, device image information relating to a device image associated with said mobile communications device using said second protocol for computing a customized upgrade process with respect to said mobile communications device based on said device image information;
• transmitting a transaction from said upgrade server to said mobile communications device in said second protocol, said transaction including information defining said customized upgrade process computed at said upgrade server responsive to said device image information, and identity information of one or more content servers having upgrade resources;
• receiving a download transaction at a content server identified in said identity information received via said second protocol, said download transaction generated by said mobile communication device and including said customized upgrade process computed at said upgrade server;
• and
• responsive to receiving said download transaction, transmitting one or more upgrade files from said content server based on said customized upgrade process to said mobile communications device.

A non-transitory tangible computer-readable medium embodying a nonvolatile memory and containing program instructions stored thereon which facilitate upgrading of device firmware when executed by one or more processors associated with a mobile communication device, the non-transitory tangible computer-readable medium comprising:

• a code portion configured to initiate a device management session with a server using a first protocol for obtaining identity information of an upgrade server adapted to operate with said mobile communications device in a second protocol;
• a code portion configured to effectuate transmission of device image information relating to a device image associated with said mobile communications device to said upgrade server using said second protocol for computing a customized upgrade process with respect to said mobile communications device based on said device image information;
• a code portion configured to process an upgrade transaction received from said upgrade server, said upgrade transaction including information operative for defining said customized upgrade process and identity information of one or more content servers having upgrade resources;
• a code portion configured to issue a download transaction to at least one of said one or more content servers based on said identity information received via said second protocol, said download transaction including said customized upgrade process computed at said upgrade server;
• a code portion configured, responsive to issuing said download transaction, to receive one or more upgrade files from one or more content servers based on said customized upgrade process;
• and
• a code portion configured to provide a status indication to said server using said first protocol upon completion of upgrading at least a portion of said mobile communications device's device image based on said one or more upgrade files.
